1 自定义DetailStoryboardSegue类继承于UIStoryboardSegue
// 这个类用于处理跳转动画
- (instancetype)initWithIdentifier:(NSString *)identifier source:(UIViewController *)source destination:(UIViewController *)destination
{
self = [super initWithIdentifier:identifier source:source destination:destination];
if (self)
{
}
return self;
}
- (void)perform
{
// 如果使用系统的转场动画则不注释,如果使用自定义转场动画则重写该放法。
// [super perform];
// 自定义转成动画代码部分
UIViewController *source = self.sourceViewController;
UIViewController *destination = self.destinationViewController;
// Create a UIImage with the contents of the destination
UIGraphicsBeginImageContext(destination.view.bounds.size);
[destination.view.layer renderInContext:UIGraphicsGetCurrentContext()];
UIImage *destinationImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();
// Add this image as a subview to the tab bar controller
UIImageView *destinationImageView = [[UIImageView alloc] initWithImage:destinationImage];
[source.parentViewController.view addSubview:destinationImageView];
// Scale the image down and rotate it 180 degrees (upside down)
CGAffineTransform scaleTransform = CGAffineTransformMakeScale(0.1, 0.1);
CGAffineTransform rotateTransform = CGAffineTransformMakeRotation(M_PI);
destinationImageView.transform = CGAffineTransformConcat(scaleTransform, rotateTransform);
// Move the image outside the visible area
CGPoint oldCenter = destinationImageView.center;
CGPoint newCenter = CGPointMake(oldCenter.x - destinationImageView.bounds.size.width, oldCenter.y);
destinationImageView.center = newCenter;
// Start the animation

[destinationImageView removeFromSuperview];
// Properly present the new screen
